Step-by-step explanation:
Find the values of x and y to determine how many solutions.
Use the elimination method. Add both of the equations.
<u>Sum:</u>
<u />
<u>Divide each side by 3:</u>
<u />
<u />
<u>Substitute y = -(1/3) into the first equation:</u>
<u />
<u>Multiply:</u>
<u />
<u>Add 2 to both sides:</u>
-5x = 0
We can determine:
(0, -1/3)
The system of equations have 1 solution.

Answer:
0.035
Step-by-step explanation:
350/10 = 35
350/100 = 3.5
350/1000 = 0.35
350/10000 = 0.035

Answer:
514 square feet
Step-by-step explanation:
2(7×4+4×5+5×7)+2(10×8+8×6+10×6)
=2*83 +2*188
=166+376
=542 square feet
7*4=28
542-28=514 square feet
